Torque converter problem...
We had a 1970 Camaro with a 540 BBC in it. We went to the track and the car went 10.70 @126mph. It has a TH400 4.11 spool with 30x12.5 ET Streets. The converter was a TCI Super Street fighter.
The car was shifted at 7,000 in second and third gear. It crossed the line at 6,800 rpm. The car was a lot slower then we were hoping.
My question is does this sound like a converter issue...maybe not locking up?
